ursodeoxycholic acid attenuates statin-induced impaired glucose tolerance

Conditions: Hyperlipidemia; Ursodeoxycholic Acid; Statin Therapy; Glucose Intolerance

Summary: the purpose of this clinical trial is to understand whether the drug ursodeoxycholic acid (udca) can prevent glucose intolerance in participants with hyperlipidemia who are taking statins. it will also assess the safety of udca. the primary questions it aims to answer are: * will udca reduce the incidence of glucose intolerance in participants taking oral statins? * will the use of udca decrease other adverse events in patients taking oral statins? participants will: * take atorvastatin combined with udca or a placebo daily for 6 months * have follow-up visits on day 40, day 110, and day 180 have their examination indicators recorded.
